Application filed May 27,

V"The present inventione relates to paint brushes, and aims to providel a novel and improved device of lthat kind for convenientlyV and efiiciently regulating 'the -flow ,of paintfrom a'reservoir to thev bristles of thev brush, while the brush is in use, said brush `being adaptedA for Vuse in painting largeV structures where it is diflicult for aV painter f to Work with an ordinary brush and bucket. Anotherfobject ifs-the provision of a novel brush having a "pair yof movable hand grip members uponl the'handle adapted -to be moved towards each other whichpermits the 'paint to Howto the bristles of thebrush, and means-for cutting ofi' the supply of paint when pressure is released from said movable hand Grip members. n Y p It is also an ob 'ect of the invention to Y provide a brushofy the kind indicated, which is simple and substantial in construction, which can be manufactured economically, `and, which will be thoroughly` efficient and practical ,in use. Y n

A further objectA of .the invention is to provide a brushkofthis characterfor use in connection with-van' yapparatus such as shown and described in my co-pending application, Serial No. 531,886, led January 26, 1922.

With the foregoing and .other objectsinV view, which will b e apparent as the description` proceeds, the invention resides in the construction and arrangement of parts, ask

' hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, withoutjdef parting from the spirit of the invention.

v The invention is illustrated in the accomvFigure 1 is a side elevation of improved brush, Y v Figure 2 is an' elevation of another side of the same, v Yj Figure 3 is a section taken online 3- 3 of Figure 2, and j Figure 4 is a cross section online 4-4 of Figure 3. ,y Y

In carrying outthe invention,the numeral 5 indicates a ferrulel rectangular in kcross lsection for receiving the bristles 6 of` the brush andkihas a centrallylocated rod? at- 192i.` semi No. 716,149;

tached thereto'. Onl opposite sides of the ferrule 5 'are secured wedge members 8 and Y 9 relatively thin and each provided with anY opening 10 in communication with the'l space occupied by the brush bristles. Cooperating 555 with thefwedge members 8 and 9 and adapted to surround the rectangular ferrule is a rectangular casing 11V having sidewalls 12 and 13 which are equipped with passageways 14 having theirV inner ends openingen theLGO Y :outer surfaces of the wedge members 8 and 9 andA normally out of registration with the openings 10. The passageways 14 are in Vcommunication' with-V feed pipes 15l which lead from Vthe connecting'fitting 16 attached 65 to a flexible hose orpipe 17 which supplies the paint'or other fluid to thewbrush under pressure'.V v j Y,

An upper guide disk or plate 18 having a central Vopening therein to slidably receive 10 the upper end of the rod 7 and also having diametrically 3 opposite openings to receive the feed pipes 15 as shown in Figure 3 is atltached inthe upper end of va cylindrical sleeve 19. A pair of collars 2O are provided 75 on the disk 18 and attached to the feed pipes 15so that said disk and feed pipes will move together as the disk is slid upon the rod 7. The lower end ofthe cylindrical sleeve 19 receives a disk 21 slidable therein, .which is 80 carried by the rod 7 and is provided vwith' Vsuitable openingsA through lwhich the feed pipes slide. p. t

Rigidly fixed to the rod 7 beneath the disk 21 is a cross arm22, the opposite endsl of 85 y which extend outwardly beyond thev sleeve 19 and are equipped with pivot members '23 for receiving oneend of the coniiectingarms 124 which are attached at their upperv ends to the finger or handgrips 25. i The upper ldisk v18'is provided with diametrically opposite I pivot members 26 for receiving the upper ends ofthe connecting arms 27 which are attached at their lower endsto the upper ends ofthe hand or finger grips 25 as clearly 95 Y shown in Figure 2 of the drawing.V It will be noted that when the membersf25. are

.gripped by the hand of the operator and pressed towards the. cylindrical sleeve 19 and through the longitudinal slots 28m opposite 100 on the ferrule and wedge members 8 and 9 ing paintto said bristles, said opennios to align the openings 'l0 and passageways 14;. This registration will permit the paint to flow to the brush bristles so that such pressure will control the flow ottpaint tothe brush bristles so that the proper quantity ot paint will be supplied at all times. A coil spring 29 interposed between the disk menibers '18 and 2l and surrounding the member 7 will return the parts to a position with the openings and passageways S and 9 ont of registration so that the flow et paint will be cut off when pressure is released from `the hand grips 25.

In operation oi my improved paint brush, the hand grips are pressed towards each other by the hand oi. the operator holding' the brush. This pressure will draw the dist: 18 down towards the disk ll compressing the spring :739, the movement et the disks or plates `causing the wedge members 8 and 9 and the rectangular casing ll to more with relation to each other, as the cross member is secured to the rod 7, thus registering the openings l0 and passageways 14. The paint under pressure can then ilow from the Heitible tube or hose 17 through the tubes to the brush bristles (i. llVhenthe hand grips are released the spring returns the various parts to their original position, thus bringing the openings 10 and passageways 14 out of registration. It will be noted that when in this position the flow of paint is absolutely cut oit diie to the binding action caused by the wedge members.

` Having thus described my invention, what I claim as new is:

l. A brush of the character described, comprising bristles, a easing about said bristles having openings therein for supply u. in said easing being normally out of register with said bristles, a handle, manually operated means upon said handle for sliding said easing upon said bristles to register said `openings with said bristles, and spring means for returning said easing to more said openings out el. registration with said bristles.
